Dataset for the national analysis of serotype‑specific dengue mortality risk in Mexico (2021–2024)

This dataset contains anonymized information from PCR‑confirmed dengue cases reported in Mexico between 2021 and 2024. It includes demographic, clinical, and virological data required to estimate serotype‑specific mortality risk. The dataset enables full reproducibility of the statistical and machine‑learning analyses performed in the study, including generalized additive models, LASSO‑regularized logistic regression, and random forest classification. This resource supports nationwide assessments of dengue mortality patterns and the evaluation of serotype‑related differences in fatal outcomes. The dataset accompanies the manuscript “Serotype‑specific mortality risk in dengue cases in Mexico: A nationwide analysis using predictive modeling.”
